Title
(EN) METHOD OF IMPROVING AN ENGINE USING A LUBRICATING COMPOSITION COMPRISING A COLLOIDAL DISPERSION OF A RARE EARTH TO CATALYSE THE COMBUSTION OF SOOT
(FR) PROCEDE DE FONCTIONNEMENT D’UN MOTEUR UTILISANT UNE COMPOSITION LUBRIFIANTE COMPRENANT UNE DISPERSION COLLOÏDALE D ' UNE TERRE RARE POUR CATALYSER LA COMBUSTION DES SUIES
Abstract
(EN)
The invention relates to a method of improving an engine equipped with an exhaust line fitted with a particulate filter, in which the particulates contained in the exhaust gas are trapped on said filter, and the trapped particulates are periodically burnt off, which method is characterized in that, for the purpose of catalysing the combustion of said particles, a composition resulting from mixing a lubricating oil with a colloidal dispersion is used as engine-lubricating composition, which dispersion comprises particles of a compound of at least one rare earth and an amphiphilic agent.
(FR)
L'invention concerne un procédé de fonctionnement d'un moteur équipé d'un pot d'échappement muni d'un filtre à particules, dans lequel on piège les particules contenues dans les gaz d'échappement sur ledit filtre et on procède périodiquement à la combustion des particules piégées et qui est caractérisé en ce qu'en vue de catalyser la combustion desdites particules, on utilise comme composition lubrifiante du moteur une composition qui résulte du mélange d'une huile lubrifiante et d'une dispersion colloïdale qui comprend des particules d'un composé d'au moins une terre rare et un agent amphiphile.
